“…This effect was also reflected in the values of the indices estimated from the information obtained. Diversity indices tend to increase in assemblages with higher richness and evenness (Shannon), which generally occur in undisturbed environments (Nuñez and Fragoso-Castilla, 2019); however, this effect was not marked in the Alameda River, except for richness.…”

In the Anthropocene, man has imposed his activities above the natural processes of ecosystems. Rivers have undergone major changes associated with urban centers, so monitoring them is important to determine their status and suitability to provide environmental services. Studies applying the community ecology approach, such as energy flow in aquatic macroinvertebrate assemblages, may be appropriate to determine their status and functioning. This study characterized an Andean river that runs across the city of Ayacucho (Peru). Water physicochemical parameters and biotic quality indices were used and compared with the abundance of trophic guild components and functional feeding groups to demonstrate that the latter are at least equally suitable to estimate water quality. The river section studied ranged from 2640 to 2900 m a.s.l. and was monitored in the wet and dry seasons. Six monitoring stations were established according to the extent of the influence of the urban center. Water physicochemical variables and macroinvertebrate abundances were determined. A Surber net was used for multihabitat sampling; macroinvertebrates were identified to genus level (in most cases) and counted to estimate relative abundances. Trophic guilds (detritivore, predator, herbivore) were formed using the genus data from identification according to the information available in Argentina, Colombia, Ecuador, Bolivia, and Peru. Functional feeding groups were set based on the classification of families. The sensitivity of trophic metrics was assessed by relating them to environmental variables and the Andean Biotic Index (ABI), the Biological Monitoring Working Party adapted for Colombia (BMWP/Col.), and the Ephemeroptera, Plecoptera, Trichoptera (EPT) indices. Environmental variables and biotic indices increased significantly in the most impacted stations, where the abundance of most taxa decreased. The components of trophic guilds and functional groups varied, and those feeding on fine particles increased in sites with a higher urban impact. The metrics based on trophic characteristics were highly correlated with the BMWP/Col and ABI indices. Therefore, these indices can be used to estimate river water quality and provide information on its functioning.

“…In the study, the environmental predictor variables of the AR model associated with aquatic macroinvertebrate communities were: Dissolved Oxygen and Turbidity (p < 0.01), with two canonical axes explaining 23 % of the total variance by Monte Carlo permutation test, this is similar to that reported by Mosquera-Restrepo and Peña-Salamanca (2019), who determined that Dissolved Oxygen and Turbidity contribute significantly as predictor variables of the aquatic insect assemblage in the Jordan River subwatershed, Colombia. The results showed that Hydrobiosidae was positively correlated with turbidity, and was associated with the stream of native forest cover (Q2-CN) due to the high ecological conditions of the habitat since it is usually found in good water quality conditions (Mena-Rivera et al, 2018;Stark, 1998); however, Gerridae was influenced by low values of Dissolved Oxygen due to its tolerance with moderately polluted environments low in dissolved Oxygen (Nuñez and Fragoso-Castilla, 2019).…”

Agricultural activities produce changes in the margins of the stream banks, causing disturbances in water quality, and in the assemblage of aquatic insect communities. The objective of this research is to evaluate the changes in the structure and composition of the aquatic macroinvertebrate community, and physicochemical variables in relation to the land use of the Guapara river, Cotopaxi province, Ecuador. Samplings were conducted during the rainy season (December to February 2018-2019) in three streams with different riparian cover: agricultural, native forest, and forest plantations, where samples of aquatic insects and physicochemical parameters were collected in situ. A total of 461 aquatic insects corresponding to 7 orders and 25 families were collected. In general, the highest abundance in order and family was presented by Ephemeroptera with 34 %, and Leptophlebiidae with 21 % respectively. According to the Ephemeroptera, Plecoptera Trichoptera (EPT) index, the highest ecological condition was found in streams with native forest cover, and forest plantations respectively, and decreased in the stream with agricultural cover; while BMWP-Cr indicated water contamination in the three streams. Hydrobiosidae (Trichoptera) were associated with high turbidity values; while Gerridae (Hemiptera) were associated with high dissolved oxygen concentrations; in addition, Ptilodactylidae (Coleoptera) preferred the Q1-CA, and Q3-CF conditions, while Leptophlebiidae (Ephemeroptera) were associated with the stream of native forest. A negative influence of agricultural activity on the physicochemical parameters of the water and on the structure of the aquatic insect community assemblage was evidenced.

Las macrófitas acuáticas juegan un rol importante en los sistemas lénticos, ya que constituyen el hábitat particular de varios grupos de insectos acuáticos y desempeñan un papel fundamental en la estructuración de sus comunidades. El objetivo de este estudio fue contribuir al conocimiento de la entomofauna acuática asociada las macrófitas en ciénagas de la cuenca media del Río Atrato, Chocó-Colombia. Durante cuatro meses se hicieron colectas de insectos acuáticos asociados a las raíces de diferentes plantas acuáticas, utilizando un cuadrante de un m2, dotado de una malla de 0,5 mm, con tres replicas por ciénaga. Simultáneamente se midieron algunas variables físicas y químicas del agua. La comunidad de insectos acuáticos estuvo compuesta por 6 órdenes, 23 familias y 36 géneros. Los órdenes más representativos fueron Hemiptera (Heteroptera) y Odonata y las familias más abundantes fueron Noteridae (Coleoptera) y Libellulidae (Odonata). El índice de diversidad presentó un rango de entre 2,39 y 2,07 bits/ind, sobresaliendo la ciénaga Plaza Seca, mientras que la dominancia estuvo entre 0,16 y 0,11. El grupo funcional de mayor abundancia fue el de los predadores. Las variables pH, temperatura del agua y transparencia presentaron diferencias significativas entre ciénagas y existieron importantes asociaciones entre la entomofauna acuática y las variables abióticas analizadas.
